Originally posted by Allez On any icons spawned by layout with these options. If you add button.cd.noCooldownCount = true in CreateAura it will disable cd in all aura icons. self.Trinket.cooldownFrame.noCooldownCount=true disables cd in this module.

Yeah, so that's exactly my point: I'd love to see another way to determine whether the trinket was used or not without cooldownFrame enabled, e.g. hiding the icon (cause I do indeed use mentioned earlier options in my CreateAuras func).

Originally posted by Monolit yeah but
button.cd.noCooldownCount = true or icons.disableCooldown = true

disables OmniCC text / spiral textures on any icons spawned by layout
